Passive Cellphone Interception system can operates on cellular frequency bands worldwide and deciphers in real-time.

Our Cellular Interception Solutions help law enforcement authorities to acquire, intercept, analyze and manage cellular communications such as voice, SMS, and Call Related Information (CRI) data. This becomes vital as terrorists and criminal elements rely upon cellular mobile communications to carry out their nefarious operations.
The system can operate on all cellular frequency bands of 2G, 3G, 4G, and 5G and can decipher A5/0, A5/2, and A5/1 encryption standards in real-time.
Stratign’s Passive Cellular Interception Solution is the most advanced ‘Off-The-Air’ interception and monitoring solution that currently exists worldwide. The system does not transmit any information and hence is completely undetectable either by the operator or by the target that is being intercepted.
